'cording to the adjustment of the actuating connection with the arm opposite the port/i, the' plunger Z being car-I ried along with the plunger m by engagement of vthescrew u with the slide n., The advance movement of the plunger m being arrested,

the face 8 of the cam engaging the slide n continues to advance the plunger Z, thereby forcing the lubricant through the port/i into the pipe j. The plungers being brought togather, Vthus expelling the lubricant between them, are then moved back together to receive another charge from the'supply-port g by the engagement of the face r of the. cam with the opposite face on the-slide o. In the return movement the plungerl, with the slide a, is actuated by engagement of the plunger Nhen the plungers have completed the` return movement, the plunger m is again advanced independently of the plunger Z by the-engagement ofthe camface fr with theoppsing trace of the slide o until the screw 'u engages the slide a, whereupon both plunger's' will' bead vanced together. The separation of the' plungers in this wa7 admits a charge of lubricant between them from the reservoir, from which it is forced bythe pressure of steam on the under side of piston c, the volume of each charge 'bei-.ig determined oy the adjustment of the screw vi. of said piston,\vliich is exposed to steam-pressure', being greater,

The area of the lower end than the area of the upper end to the extent of the area of the piston-rod d., subjects the lu brican t what greater than that against which it is to be ii'ed and` insures its ow through the connection and port f/ into the vspace between the plungers K and m when they are brought into receiving position. This is of prime importance with thick` stiii' lubricants, which do l no not iow readily endwith which it is impracticabie to use check-valves. I

in my improved apparatus the lubricant is forced from the reservoir by Huid-pressure overbnlancing the pressure agiinst whichit is to be fed and is measured-outside of the reservoir and positively delivered in exact predetermined charges to the feed pipe or passage lending' to the hearing or other part to be lubricated. iiy varying the length of the arm fr or vthe distance of its actuati ng connection from the axis on which it swings the frequency of the delivery of the charges of lu brisent may be varied; and by adjusting the screw n. the size or volume ot' the charges v be varied., thereby regulating .theffeed in tiro ways.

The plunger`m 4is connected with a lever carried by the slide n', with --which the other plunger Zisconnected. IThe' lever eis ulcrumed to an'arm 2, which is pivoted to the slide1 n and a4 segment of a worm-gear', meshing with a worm 4,journaled. ontsaid slide and .serving to adjust the fulcriim of the lver e. A fork-lever 5, ,embracingl the cam q, is ful'crumed to the slide n. and formed with a transverse groove or recess, in which a block 6, pivdted tothe lever z, is adjustably held. In this form of Athe lubricatorgthe rotation of the'cam qiin the direction indicated 'by the arrow actuates the slide n', which carries the plunger l and the levers v.e and 5, and

thus produces the simultaneous movement of botbi plungers l and vn, back and forth from oneiportto thefother. At or near the limits of the movement of the andv operates through the lever z to Amove the plunger m independently'of th'e plunger l, sor 'as to separate them at the supplyport g and bring them together at theldischarge-port k. The degree otseparation of the plungers and the size or. volume of the charge of lubricant is determined and regulated by the adjustment of the worm 4. In other respects the operation of this form of the lubricant is essentially the same as that 'shown in the preceding figures.

Various changes' other than those specified may be made in thedetails of, the apparatus Iwithout departure from the principle and intended scope ot' the invention.
